Spring is here, and you’re ready to bring your garden back to life. Maybe you picture colorful flower beds lining your walkway, bursts of bright blooms in patio containers, or a neatly landscaped yard that looks effortlessly beautiful.

But there’s a problem—you’re not sure what to plant.

If you’ve ever walked into a garden center and felt overwhelmed by the sheer number of flower choices, you’re not alone. One of the biggest decisions gardeners face is whether to plant annuals or perennials. Some flowers bloom for one season and then disappear, while others come back year after year. Which is the better choice for your yard?

We understand that you want a beautiful, thriving garden without spending all your free time maintaining it. That’s why we’re here—to help you make the best choice based on your goals, budget, and lifestyle.

By the time you finish reading this, you’ll know exactly what annuals and perennials are, their pros and cons, and how to decide which is right for your spring garden.

What Are Annual Flowers?

The One-Season Wonders

Annual flowers live for just one growing season. They sprout, bloom, and die all in the same year, meaning you have to replant them each spring. While that might sound like extra work, there’s a reason people love annuals: they deliver big, bold color all season long.

Popular Annuals for Tennessee Gardens

Here in Oak Ridge and Knoxville, we get warm, humid summers, so choosing the right flowers for our climate is key. Some great annuals that thrive in this area include:

  • Petunias – A favorite for hanging baskets, flower beds, and containers. Available in just about every color.
  • Marigolds – Bright yellow and orange flowers that repel pests naturally.
  • Zinnias – Perfect for cut flower arrangements and attracting pollinators.
  • Impatiens – Love the shade and produce non-stop blooms.
  • Pansies – A cool-season annual that can handle early spring chills.

Why Homeowners Love Annuals

  • Instant impact – You don’t have to wait for years to see full, bright blooms.
  • Extended bloom time – Many annuals bloom from spring to fall with proper care.
  • Flexible design options – Want a fresh new look every year? Annuals let you experiment with colors and layouts.

The Drawbacks of Annuals

  • Higher cost over time – Since they don’t return, you’ll need to buy and plant new flowers each year.
  • More maintenance – They often need regular watering and fertilizing to stay healthy.
  • Short lifespan – Once the season is over, they’re gone for good.

What Are Perennial Flowers?

The Long-Term Investment

Perennials are flowers that come back year after year. Unlike annuals, they don’t die at the end of the season; instead, they go dormant in the winter and regrow in the spring. This makes them a low-maintenance, long-term investment for homeowners who want a more established landscape.

Popular Perennials for Tennessee Gardens

Some of the best perennials for our region include:

  • Daylilies – Almost indestructible and come in a variety of colors.
  • Coneflowers (Echinacea) – Attract bees and butterflies while resisting drought.
  • Black-eyed Susans – Bright yellow, daisy-like flowers that bloom from summer to fall.
  • Hostas – Ideal for shady areas, offering lush green foliage.
  • Peonies – Large, fragrant blooms that make stunning cut flowers.

Why Homeowners Love Perennials

  • Cost-effective – Plant them once, and they return every year.
  • Low maintenance – Once established, they need less watering and care than annuals.
  • Improve with age – Many perennials grow larger and stronger each year.

The Drawbacks of Perennials

  • Limited bloom time – Most perennials bloom for only a few weeks to a couple of months.
  • Slower to establish – Some take a year or two to really fill in and reach their full potential.
  • Less flexibility – If you plant a perennial in the wrong spot, it’s harder to move or replace than an annual.

Annuals vs. Perennials: Which Is Right for Your Garden?

The answer depends on a few key factors:

  1. Your Budget
  • If you want instant impact and are willing to replant each year, go with annuals.
  • If you want a long-term investment that saves money over time, perennials are the better choice.
  1. Your Maintenance Preferences
  • Don’t mind regular watering, fertilizing, and replanting? Annuals will give you season-long color.
  • Prefer a low-maintenance garden? Perennials require less effort once established.
  1. Your Design Goals
  • If you love experimenting with new colors and layouts each year, annuals are perfect.
  • If you want consistent structure and returning blooms, perennials are the way to go.

Why Not Both? Mixing Annuals and Perennials

For most homeowners, the best approach is a mix of both.

Imagine this: You plant perennials to create a solid foundation for your garden—like cone flowers, black-eyed Susans, and daylilies. Then, each spring, you add

annuals like petunias and zinnias to fill in gaps, add bursts of seasonal color, and refresh the look.

Caring for Your Spring Garden: A Few Key Tips

  1. Water wisely – Most flowers need about one to two inches of water per week.
  2. Feed your plants – Annuals love regular feeding, while perennials benefit from slow-release fertilizer.
  3. Mulch matters – A layer of mulch helps retain moisture and reduce weeds.
  4. Deadheading helps – Removing spent blooms keeps flowers blooming longer.
